Security audit

Video Toolkit Free

Security checks across malware telemetry and agentic risk

Overview

This is a local FFmpeg video-processing skill with disclosed command execution and no evidence of hidden data access, exfiltration, persistence, or destructive behavior.

Install only if you are comfortable letting an agent run local FFmpeg/Whisper commands on videos you provide. Review output filenames before processing to avoid overwriting files, and approve any brew, apt, winget, or pip dependency installation manually.

Context-Inappropriate Capability

Medium
Confidence
90% confidence
Finding
The skill introduces `ping`-based network diagnostics even though its stated purpose is local video processing. Unnecessary network-capable instructions expand the skill's operational scope and can normalize executing unrelated connectivity checks, which is risky in an agent context with `exec` access.

Vague Triggers

Medium
Confidence
86% confidence
Finding
The trigger scope is overly broad and includes generic phrases such as 'when' and wide media-processing terms, which can cause the agent to invoke this skill outside its intended context. Overbroad activation is dangerous because the skill has `exec` capability and may run shell commands in situations unrelated to the user's actual intent.

Missing User Warnings

Medium
Confidence
92% confidence
Finding
The documented commands create and overwrite output media files without explicit warnings about clobbering existing files or modifying user data. In an agent environment, this can lead to accidental data loss, especially if output names collide with existing files or if users assume a dry-run style operation.
